'v its outlet end.v An' internal screw thread I8 is Myinvention relatesto improvement in liquid dispensing nozzles of the type generally usedfor dispensing motor fuel. Nozzles of this character are provided withnozzle-suspending means adapted for suspending the nozzle upon abracketl formedlon ya connection head which is secured on the upper endof a standard, or supply pipe, and to which head one end of a hose isattached, with the opposite end of the hose attached to a nozzle,whereby the nozzle may be readily suspended upon the bracket when not inuse.

'Ihe object of my invention is to provide a nozzle with a strainer forstraining the liquid as it is discharged from the nozzle, and providenovel means for mounting the strainer upon the nozzle.

A further object is to associate the strainer and the nozzle-suspendingmeans in such a manner that the nozzle cannot be suspended upon thebracket unless the strainer is properly replaced upon the nozzle afterit has been removed for cleaning purposes.

These together with various other novel features of construction andarrangement of the parts, which will be more fully hereinafter describedand claimed, constitute my invention.

Referring to the accompanying drawing:

Fig. 1 is a longitudinal sectional view of my improved nozzle, showingdevices in elevation and adapted for suspending the nozzle.

Fig. 2 is an enlarged sectional perspective view of the strainer and thesleeve upon which the strainer is secured, shown detached from thenozzle.

Fig. 3 is a perspective view of the smooth end after the sleeve andstrainer have been removed.

Fig. 4 is a sectional perspective View showing a modified form of thenozzle-suspending means.

In the drawing in which like reference characters refer to like parts,Fig. 1 shows a dispensing device which includes a standard or supplypipe 6, secured in an erect position and connected with a source ofliquid supply. A fitting in the form of a head I is connected with thepipe 6, a hose 8 is connected with the head, and a nozzle I is connectedwith the free end of the hose in the usual manner.

The head 1 is provided with a bracket I2 for suspending the free end ofthe nozzle upon the head 1, when the nozzle is not in use. Said bracketI2 is provided with a side opening I3, through which the flanged end ofthe nozzle I0 may be readily inserted and supported by lips I and I6,forming part of the bracket I2.

In carrying out my invention I employ a nozzle I0 having a smooth outercylindrical surface at screen, or strainer, V2,2

formed in the nozzle, as shown in Fig. 3.

-A sleeve 20 is provided with an external screw thread 2I and is adaptedto be engaged by the thread I8 of the nozzle. A cylindrical wire meshoccupies the bore of the,

sleeve y2I1`iand is secured to the sleeve by means of solder 23. l

The strainer 22 fits loosely into the outlet end of the nozzle I0 andextends into the latter a sufficient distance beyond the sleeve 20 topresent a large filtering or straining surface. The

inner end of the strainer 22 is pinched together and secured by solder24.

The sleeve 20 is provided with a flange 25, or other suitableprotuberance, which extends beyond the periphery of the nozzle, andforms bracket engaging means, adapted for suspending the nozzle from thebracket I2, as shown in Fig. 1.

The sleeve 20 and the ange 25 are preferably made in one piece, as shownin Figs. 1 and 2. The sleeve and flange may be formed separately, asshown in Fig. 4, wherein the sleeve 28 is provided with an enlarged head28, adaptedfor engaging a flange, or washer, 3U, and securing the sameupon the end of the nozzle. washer, 30 projects beyond the diameter ofthe nozzle and forms the bracket engaging means by which the nozzle maybe suspended upon the bracket I2, when the sleeve and strainer aresecured upon thenozzle.

The novel means for mounting the strainer upon the nozzle insures thereplacement of the strainer upon the nozzle after the strainer has beenremoved for cleaning the same. By combining the sleeve and strainer as aremovable unit, and arranging the sleeve for controlling the position ofthe flange'25, or the flange 30,' relatively to the nozzle, the nozzlecannot be suspended upon the bracket I2 until the sleeve and strainerare properly attached to the nozzle.

Should the attendant neglect to attach the sleeve, carrying the strainer22, to the nozzle it will be impossible for him to suspend the nozzleupon the bracket I2, due to the smooth surface of the nozzle at itsdischarge end.

My invention insures the nozzle always being provided with a fuelstrainer properly installed in the nozzle.

Various changes in the construction and arrangement of the parts may bemade without departing from my invention.
